Question

A scientist has proposed a model of a two-particle system, consisting of an electron and a proton. In this model the scientist mentioned an electron as a point particle that is orbiting at an average distance of 5.28×10−11m from the proton. We can view the system by imagining that the proton is at the center of a clockface, and that the electron is moving clockwise in a circle. It is given that the speed of the electron is 4.79×106m/s . Determine the magnitude of the electric field that the electron produces at the center of the clock face

Answer 1

The magnitude of the electric field produced by an electron at the center of its orbit around a proton can be calculated using Coulomb's law, where the electric field (E) is E = k * |q| / r^2 with known values for the electron's charge and the orbit's radius.

Step-by-step explanation:

To determine the magnitude of the electric field that an electron produces at the center of a circular orbit (which can be modeled like a clock face with the proton at the center), we can apply the principle that the electric field (E) produced by a point charge is given by Coulomb's law. Specifically, the magnitude of the electric field due to a point charge is E = k * |q| / r2, where k is Coulomb's constant (8.99 × 109 N·m2/C2), q is the charge of the electron (-1.602 × 10-19 C), and r is the distance from the charge to the point where the field is being calculated—in this case, the radius of the electron's orbit (5.28 × 10-11m).

Calculating this, we get:

E = (8.99 × 109 N·m2/C2) * (1.602 × 10-19 C) / (5.28 × 10-11m)2

The calculations yield the magnitude of the electric field at the center of the clock face due to the orbiting electron.
